This paper develops a network-based framework to examine the spatiotemporal dynamics of aviation emissions and their policy implications. Using the Yangtze River Delta as a representative urban agglomeration, we construct intercity emission networks from flight-level data (2019—2023). The analysis highlights persistent hub concentration, uneven spatial distribution of emissions, and distinct short- and long-term drivers of emission dynamics. More broadly, the findings demonstrate that aviation decarbonisation requires more than technological innovation: managing network connectivity, rebalancing hub dominance, and integrating alternative transport modes are equally critical. The proposed framework offers a transferable approach for linking aviation networks with environmental outcomes and provides insights for designing coordinated emission reduction strategies in other regional and national contexts.</div></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"134 ","pages":"Article 104713"},"PeriodicalIF":6.3,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148184452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Borrowing from Raymond Williams, I argue that to refuse unsustainable transport – which the UN Decade of Sustainable Transport sets out to do - we have to refuse more than unsustainable transport, including the systems of oppression, and structures of fossil dependence and wealth accumulation. To do this requires that we unsettle intersecting root causes of unsustainability, and locate resources of hope for the coming decade and beyond.</div></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"134 ","pages":"Article 104725"},"PeriodicalIF":6.3,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148184585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For instance, freedom equity is particularly important for non-local <em>hukou</em> holders and highly educated respondents, while ease equity matters more for women and low-income groups. We also find that mode diversity equity increases social exclusion among retirees, suggesting that a perceived advantage in modal choice may not necessarily translate into more inclusive mobility in later life.

However, existing studies predominantly focus on descriptive, static, and urban-core-based analyses of accessibility coverage, neglecting predictive insights into how this policy shift might impact systemic spatiotemporal disparities in suburban and peri-urban contexts. This study introduces a novel optimization-based evaluation framework that integrates temporal accessibility metrics to assess how different policy objectives—minimizing average travel time versus maximizing population coverage within 15-, 30-, and 45-min thresholds—shape spatial equity across urban-suburban gradients. Leveraging high-resolution data on COVID-19 testing sites in 10 Chinese megacities, we identify persistent suburban accessibility deserts, particularly under nighttime conditions, and quantify the implications of different planning strategies. Our findings reveal that proximity-driven goals, while effective in boosting 15-min coverage, often fail to mitigate temporal and spatial inequities, especially in underserved suburban areas. In contrast, efficiency-driven approaches not only enhance overall travel performance but also deliver disproportionate benefits to marginalized populations in peripheral zones. This study challenges proximity-centric assumptions embedded in current 15mC discourse and highlights the need for context-sensitive, temporally-aware equity metrics. Our methodological innovations offer transferable tools for equitable public service allocation and provide strategic guidance for suburban planning under both crisis and normal conditions.</div></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"132 ","pages":"Article 104581"},"PeriodicalIF":6.3,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146147668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study uses mobile phone signaling data from the Shenzhen Metropolitan Area and proposes a two-stage regression framework. In the first stage, a flow-based geographically weighted regression model is used to estimate distance decay coefficients; in the second stage, random forest combined with SHAP analysis is applied to examine the influence of the built environment. The results show that intercity commuting decays faster than intracity commuting and exhibits spatial heterogeneity. Along city boundaries, short-distance intercity commuting shows quick decay due to limited transport supply and administrative barriers; along the perpendicular direction, medium- and long-distance intercity commuting is influenced by cross-border coordination, high-level transport infrastructure, and housing price differences, which reduce decay, but poor connectivity or high combined costs of housing and transport can still increase it.

The algorithm dynamically incorporates the multiple heterogeneous relationships between nodes and edges in the transportation network into the action selection process, significantly enhancing the model's ability to capture key paths. Additionally, the algorithm introduces a node decomposition method to ensure consistency in the reward of action selection, avoiding conflicts with the requirements of the Bellman equation, effectively simplifying the state space management in path planning. Finally, this paper thoroughly examines the multi-objective impact of cost, time, and carbon emission on multimodal transport path selection. It further explores the comprehensive impact of railway freight subsidies, carbon tax policies, and uncertainties in transportation time on the final transportation scheme.
